rubber pads.

4.4 Connection of cables

Caution

• Request an installation company or your dealer to carry out wiring.

If wiring is incomplete, shock hazard or injury may be caused.

• Class D grounding construction is mandatory. Otherwise, shock hazard may be caused.

For preventing shock hazard, fire and injury, be sure to observe the following.

• Before wiring, be sure to turn off the primary power supply. If this is neglected, you may receive and

electric shock.

• For grounding, use a 600 V-IV wire having diameter of 2 mm

or more and an adequate dielectric

strength.

• Connect the power supply which meets the rating of product. Connection of other power supply may

cause a fire.

• Select the diameter of input and output wires, which matches the rated current of gas analyzer.

• Be sure to use solderless terminals for connection to the input and output terminal block.

• Use the terminal block for branching the output wire.

• Be sure to fix the input and output wires onto the floor, wall surface, etc. and use a protective device for

wires.

The lead-in for AC power cables and outlet for signal wires are provided at the bottom of the analyzer or else

at the specified place. Connect AC power cables and output signal wires according to the separately issued

wiring diagrams.

Note: Avoid connecting the analyzer power supply near devices such as high-frequency heating fur-

nace or electric welder which greatly disturb the power waveform, and avoid sharing the same

power lines with such devices. Class D grounding construction (100W ground resistance) is

required.

4.5 Connection of pipes (refer to piping instructions in Fig. 4-1 and separately issued approval

drawings)

(1) Connect gas pipe between the gas extractor and the analyzer inlet (sample gas inlet). Use a joint, etc.

for ø10/ø8 Teflon pipe when connecting to ensure there will be no leakage.

(2) Additionally tighten the joint section if necessary

– 4 –

Fig. 4-1 Piping procedure

Note 1) To prevent aspiration of leaked air

Note 2) Install so that pipe end comes to nearly center of flue and is at right angle to the gas flow.

Note 3) Peel off heating pipe by about 2m in order to air-cool measured gas.

Note 4) Provide an inclination of 15° or more on the gas pipe so that drain will not accumulate in the event

of power failure, etc.

Note 5) Exhaust and drain share the same output. In the case of indoor installation, provide a drain pot

and carry out drain separation, and exhaust air outside (pipe inner diameter should be ø8 or

more).

Note 6) Use this when utilizing a heating pipe. (Maker : Fujikin, Japan)

Note 7) The gas pipe (ø10/ø8 teflon tube) should be inserted directly into the gas conditioner.

Note 8) In outdoor application or in a cold district, protect the drain pot and pipes with a heat insulating

material, etc. to prevent drain from freezing in winter.

6.4 Airtightness test

(1) Piping inside panel

Since airtightness is confirmed during tests before shipment, an Airtightness test during trial run is

usually unnecessary. When a long time has passed after shipment, then carry out the following proce-

dure.

(a) Close the drain port.

(b) Connect standard gas to the sample gas inlet.

of a manometer).

(d) Flow standard gas gradually, and after reaching a pressure of about 1961Pa, close the needle valve

of the pressure regulator.

(e) Check the water level at the air suction port of the conditioner, and if the drop in the level in less

than 147Pa/min, then the error due to insufficient airtightness is negligible.

(f) If a leak is present when measuring a harmful gas, make a check by applying soapy water to the

normal pressure section while aspirating outside air.

(2) Piping outside panel

Thoroughly check the tightened condition of pipe joints. If necessary, apply pressure from the extrac-

tor outlet side and make a test as in the preceding item (1).

(3) If the airtightness is insufficient, make a test on each section, find the faulty location and make it

completely airtight. If the faulty location is before the aspirator, then air enters the gas pipe midway to

cause a drop in the indication.

8. CALIBRATION

8.1 Kinds of standard gas

8.1.1 When not using zirconia O

sensor

(1) Zero gas: N

or atmospheric air/instrument air depending on specification (when without verifi-

cation stipulated in the laws for measurement and weighing)

(2) Span gas: Gas of 90% or more full scale for each component, remainder is N

(span gas for low

range will be delivered unless otherwise specified)

8.1.2 When using zirconia O

sensor

(1) Zero gas: Air (Span gas of the O

analyzer in the laws for measurement and weighing).

(2) Span gas: 1 to 2% O

, remainder is N

. (Zero gas of the O

analyzer in the laws for measurement

and weighing).

Gas of 90% or more full scale for other than zirconia O

sensor, remainder is N

Note: For separately calibrating the low and high ranges of the zirconia O

sensor, supply 9 to

10% O

and the remainder N

for the low range (10%) and use air for the high range

(25%).

8.2 Preparation of standard gas

The standard gas to be used for calibration is delivered in a separate package from the locker.

Check the kind of standard gas to be used according to the sampling system diagram, and set it at the

prescribed location.

Before starting calibration, attach a pressure regulator to the standard gas.

8.2.1 How to mount pressure regulator for standard gas cylinder

(1) Before mounting a pressure regulator to the gas cylinder, clean the gas cylinder adapter. Entry of

dust into the pressure regulator may result in gas leaks.

(2) If packing is not inserted in the mounting nut for the cylinder or it is damaged, replace it with

supplied spare one.

(3) Use a spanner of a proper size, fasten the cylinder mounting nut to the gas cylinder. Mount

supplied joint to the outlet according to Item “Sampling system block diagram”.

(4) Loosen the pressure controls and then tighten the outlet controls.

(5) Open a valve of the gas cylinder, and the pressure gauge on the high pressure side indicates a

pressure of the gas cylinder by flowing gas into the pressure regulator.

(6) Turn the pressure controls clockwise to increase the secondary pressure; adjust the pressure con-

trols so that a pressure gauge on the low pressure side reads 30 kPa.

(7) Open the outlet controls to release gas.

Danger

• When handling standard gas such as calibration gas, read the instruction manual for the standard gas for

correct handling. Special care should be taken when handling hazardous gas such as CO gas and the like

to prevent poisoning.
